Yamaha Clarinova CLP920 Sustain Pedal not Working

Hello there - I have a beautiful 20 year old Yamaha Clarinove CLP920 - it’s in perfect working order, except the sustain pedal no longer works!.
I’ve disassembled and tried to clean up the relevant electronic circuits but to no avail.

Any assistance much appreciated! thanks nick
